Cancer is one of the leading causes of death, responsible for 16% of deaths worldwide in 2018.
Immunotherapy is a type of cancer treatment that helps the immune system to fight cancer. Immunotherapy with drugs called checkpoint inhibitors have begun to transform cancer treatment, bringing about significant improvements. However, they have only been proven effective for a small subset of cancers and specific patient groups. Hence, an urgent and significant healthcare need remains to support cancer patients who do not respond to first- generation checkpoint inhibitors.
GRWD5769 is a potential new treatment for advanced or metastatic solid malignancies. GRWD5769 works by stopping an enzyme in the body, called endoplasmic reticulum aminopeptidase 1 (ERAP1), from working. ERAP1 is part of how the body recognizes the presence of a cancer tumour and helps trigger the immune system to fight the cancer. However, in patients with cancer, the immune system cells can become exhausted and no longer work effectively. By blocking ERAP1 it makes the tumour look different to the immune system and so the immune system starts fighting the cancer again. Giving the study drug
intermittently may also help prevent the immune system cells from becoming exhausted. Studies have been conducted in animals which support the use of GRWD5769 in humans for the treatment of advanced solid tumours in a broad range of cancer types. GRWD5769 has the potential of producing clinically meaningful improvements in monotherapy and in combination with therapy like cemiplimab (Libtayo®) by enhancing the antitumour immune response.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

21 Feb 2023 30 Sep 2025

This study consists of Module 1 (Parts A to D), which will look at the effects of GRWD5769 when given alone and Module 2 (Parts A to C) which will look at the effects of GRWD5769 when given in combination with another anticancer drug called Libtayo® (cemiplimab).

GRWD5769 is an experimental drug, and this is the first time it is being tested in humans and it is not known whether GRWD5769 alone or in combination with cemiplimab will improve a participant’s cancer. It is hoped that the information learned from this study may help future patients with cancer. This research may lead to new or improved drug treatments in the future. Risks:
This is the first time GRWD5769 is given to humans. Whilst, based on animal data, GRWD5769 has not been linked to significant safety issues, the safety in humans is not known. The dose levels to be used in this study will not exceed the dose levels that were tolerated in animals. Each time a new dose of GRWD5769 is given to a participant, a minimum of 48 hours will be allowed to check for safety before any other participants receive that dose. A safety review committee will also oversee the dose escalation phases and decide whether it is safe to test a higher dose. GRWD5769 is potentially phototoxic. Participants are provided with instructions to minimise this risk. GRWD5769 may also interact with other drugs, so participants are not allowed to take certain medications. The effects of GRWD5769 on the unborn child or newborn baby is unknown so all precautions are taken to exclude pregnant or breast-feeding women and to ensure appropriate contraception is used.
Cemiplimab is a licenced medication, but in this study may be used in unlicenced indications and it has not been given with GRWD5769 before. Cemiplimab can cause potentially serious side effects associated with inflammation. It can also be associated with infusion reactions.
Administration of cemiplimab will be managed by experienced hospital staff, according to established guidelines and patients will be informed about the risks. There is the possibility of additional or worse side effects by giving both GRWD5769 and cemiplimab together. This will be monitored and overseen by the safety review committee.
The study requires a number of blood draws to be made and a significant amount of blood to be collected as part of assessing levels of GRWD5769 in the blood and the potential effects of GRWD5769. Patients may also need to stay in hospital overnight on a few occasions where late night and/or early morning samples are needed. This will be made clear to patients when they consider if they want to take part in the study. There can be pain or bruising at the site where blood is drawn from, which Study staff will monitor and manage. There are potential risks associated with some of the other study interventions, such as pain and bleeding after a biopsy procedure. CT, MRI and bone scans needed to monitor disease use ionizing radiation, which can cause cell damage that may, after many years or decades, turn cancerous, though the chance of this happening is extremely small.
